Sexual activity which does not result in offspring is not included in this concept. On the other hand, if offspring begin to develop, but never finish (e.g., it just hasn't finished yet, or the mother dies, or the offspring is aborted, or the offspring doesn't survive to independence, etc.), then that is still considered an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjpoJwpEbGdrcN5Y29ycA" class="cyc_term">SexualReproductionEvent</a> but an incomplete one. The example of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjpoJwpEbGdrcN5Y29ycA" class="cyc_term">SexualReproductionEvent</a> most familiar to most people is when two mammals, one male and one female, mate; sperm from the male combines with one or more eggs inside the female and the resulting offspring develop(s), inside the female parent and dependent upon her for nutrition, until it/they is/are born. However, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjpoJwpEbGdrcN5Y29ycA" class="cyc_term">SexualReproductionEvent</a> is more general than that, and would include these examples: Two birds mate; the female lays one or more eggs; both parents incubate the eggs until they hatch. Two fish engage in courtship; the female expells her eggs; the male expells his sperm on top of them, and they swim away leaving many fertilized eggs to develop into juvenile fish. One oak tree's flowers give off airborne pollen; some grains land on the stigma of another tree's flower and fertilize the ovary inside, which then develops into an acorn which is shed by the female parent at the end of summer.

BiologicalDestructionEvent biological destruction AnimalMigration migration The collection of regular, species-linked movements of an animal or group of animals from one place to another, usually with a return to the starting point after a certain period of time. In some species, the migration cycle occurs once in a lifetime, while others migrate annually on a seasonal basis. Migration is typically linked with an animal's reproductive cycle (as in salmon), but may also involve seasonal relocation to a more hospitable climate and/or more plentiful food supply. For example, many birds exhibit seasonal migration; e.g., native Northeastern U.S. birds that spend their winters in the Southern U.S. A specialization of both <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv4jqZJwpEbGdrcN5Y29ycA" class="cyc_term">PhysicalDestructionEvent</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVisLpwpEbGdrcN5Y29ycA" class="cyc_term">KillingByOrganism</a>.

This is the collection of all and only those collections <code>COL</code> such that any thing's being an instance of <code>COL</code> depends on the current state of the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjqoZwpEbGdrcN5Y29ycA" class="cyc_term">CycKB</a>. Such a <code>COL</code> corresponds to a property defined (at least partly) in terms of the contents, features, or implementation of the Cyc Knowledge Base itself, as opposed to a property that "exists out there" in the KB-independent world. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvV281JwpEbGdrcN5Y29ycA" class="cyc_term">CycLAssertion</a> is a KB-dependent collection, membership in which requires of a given CycL sentence that it has in fact been asserted to the KB. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAoJwpEbGdrcN5Y29ycA" class="cyc_term">CycLSentence</a> is also KB-dependent, as being a CycL sentence requires being composed (ultimately) out of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvu6KTZwpEbGdrcN5Y29ycA" class="cyc_term">CycLReifiedDenotationalTerm</a>s (and perhaps variables) -- i.e. terms that are currently reified in the KB. Conversely, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv5ddsJwpEbGdrcN5Y29ycA" class="cyc_term">Sentence</a> is not a KB-dependent collection.
